Michael Jeffery Jordan, portrayed by Michael Jordan, is a determined 10-year-old boy with aspirations of becoming a renowned NBA player. Fast forward to 1993, where Michael decides to retire from basketball, seeking a new path in professional baseball, although he soon discovers that this new endeavor isn't his forte.
Meanwhile, in a distant part of outer space lies a sinister amusement park known as "The Planet Moron Mountain Theme Park," ruled by the ruthless Mr. Smackhammer. Frustrated by dwindling attendance, he hatches a plan to create a captivating new attraction. His solution? To enslave the famous "Looney Toons," a crew of zany cartoon characters residing in the whimsical 2D world beneath Earth. To execute this scheme, he dispatches his diminutive yet cunning alien minions, known as the Nerdlucks—Pound, Bang, Bupkus, Blanko, and Nawt—to capture the Toons.
When the Nerdlucks land in the cartoon universe, they inadvertently disrupt a chase between Bugs Bunny, the ingenious leader of the Toons, and his nemesis, Elmer J. Fudd. After a comical mishap involving their spaceship, Bugs convenes all the Looney Toons for an emergency meeting at the Toon-Town Schlesinger Union Hall. The Nerdlucks, presenting their devious plan, threaten to take the Toons as captive attractions. Cleverly, Bugs proposes a challenge: a basketball face-off against the aliens, knowing their lack of physical prowess. The Nerdlucks, however, are not to be underestimated; they hatch a scheme to infiltrate the NBA and steal the abilities of prominent players like Charles Barkley, Patrick Ewing, Shawn Bradley, and Muggsy Bogues, transforming into the formidable Monstars.
Back in the real world, Michael's life takes another turn when he crosses paths with the well-meaning but clumsy publicist, Stanley "Stan" Podolack, who strives to be a supportive friend and assistant. When Michael goes golfing with Stan, along with actors William "Bill" Murray and Lawrence "Larry" Bird, an unexpected twist occurs: Bugs Bunny uses his special powers to contact Michael. He reveals the dire situation involving the Monstars, and though initially hesitant due to his time away from basketball, Michael eventually joins forces with the Looney Toons.
As Michael immerses himself in their animated world, he encounters Lola Bunny, a basketball-savvy rabbit who catches his attention. Realizing he needs his trademark sports gear, Bugs and the envious Daffy Duck sneak into Michael's home to retrieve his essentials. However, a narrow escape from Michael's bulldog, Charlie, adds to the excitement, aided by Michael's kids.
The epic basketball showdown kicks off at the Toon Stadium Arena. The Monstars take an early lead, but Michael and the Looney Toons rally back with the help of a magical sports drink known as "The Secret Stuff" (which is merely water). As the game progresses, stakes rise, leading to deals where Michael must confront his own fate at Moron Mountain should they lose. After a series of thrilling and injury-riddled exchanges, with even Stan and Bill joining the fray, Michael scores the final shot, securing victory for the Toons.
Ultimately, the Monstars relent, sending Mr. Smackhammer careening to the moon upon realizing the Toons' power. The Nerdlucks, seeking acceptance, attempt some antics, only to face a comical end. Michael returns triumphantly to baseball, and a budding romance blossoms as Bugs shares a kiss with Lola Bunny.
The story culminates in 1995 as Michael reclaims his basketball career, graciously returning the extraordinary gifts back to the NBA. The film closes on a note of triumph and nostalgia, reminding audiences of the enchanting blend of animation and sports.
